Right, I'm an electrical noob but I've just replaced a dimmer switch in a room three times and every time has presented a new and interesting problem.
Currently, I've put a programmable Varilight V-com dimmer in (1 gang) and when I switch it on, the light soft-starts up to its maximum brightness. But the dimmer function doesn't work after that.
It has all sorts of instructions for resetting the mode, maximum brightness etc, but it doesn't do anything.
Any ideas? Or is it fucked and need replacing?
